This past April, hundreds of transit maintenance workers descended on the Broadway Line to inspect, repair and replace vital components, in addition to cleaning and painting. Workers were able to remove thousands of pounds of scrap and debris from the tracks, replace hundreds of tunnel light bulbs, service closed circuit television equipment and perform maintenance on elevators and escalators.

FASTRACK was introduced in January 2012, devoting four straight weeknights to perform maintenance work in tunnels, stations and on tracks, completely suspending service within a given line segment for a seven-hour period between. This gives free access to the system, allowing an army of maintenance workers to perform dozens of tasks without the concern of having to "clear up" to allow trains to pass.

The next FASTRACK overnight closure will be on the D Line north of 161st Street for four consecutive weeknights beginning July 15.
